SIGNAL-LANTERN.

Specification of Letters Patent.

, atcnted Dec. 21, 1909.

Application filed March 1, 1909. Serial No. 480,700.

To alt whom it may concern:

mitt-red ring 8 is provided.

lle it known that I, Gnonon l Bnowivn, a i just outside of the lamp wellI, and is adaptsubject of the King of Great Britain, residing in thecity and district of Montreal, in the Province of Quebec, Canada, haveinvented certain new and useful Improvements in Signallianterns; and Ido hereby declare that the following is a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertaius to make and use the same.

The invention to be hereinafter described relates to signal lanterns,and more particularly to a means for giving three signal colors by thesame lantern.

Broadly speaking, it comprises a framework, a globe in the framework, aventilator chimney above the globe, a lamp well below the globe, coloredslides movably mounted in the chimney and lamp well, means for adjustingthe slides, and means for locking the slides in adjusted position.

In order to more clearly disclose the construction, operation and use ofthe invention, reference should be had to the accompanying drawingsforming part of the present application.

Throughout the several figures of the drawings, like referencecharacters designate the same parts.

In the drawings: Figure 1 is a side elevation of the lantern; Fig. 2 isa perspective of the upper slide and its actuating ring; Fig. 3 is asimilar view of the lower slide and its actuating ring; and, Fig. at isa vertical central section through the lantern.

The lantern frame and globe may be of the usual and well known type usedby all large railways. Near the lower part of the frame, and directlybeneath the bottom of the globe, is suspended a lamp well 1, providedwith a tubular upwardly extending cylinder 2, adapted to receive thefont 3. The font is provided with a circumferential groove a, adapted toseat resilient spring fingers 5 secured to the inner surface of thecylinder. In this way, the font is securely held in position while thelantern is swung to give various signals. Between the cylinder 2 and thelamp well 1 is movably disposed a cylindrical glass sleeve 9, coloredred or green. This sleeve carries spring fingers 7, which act to spaceit from the lamp well. In order to raise and lower this sleeve, a

ed to slide over the same. Rods 10 travel freely in grooves 11, andconnect the ring and lower end of the sleeve. Consequently, in order toraise the sleeve, it is only necessary to raise the ring to the tops ofthe grooves 11.

The ventilator chimney comprises two concentrically arranged cylinders12 and 13, the inner one being suspended from the outer one, and theouter one being provided with a plurality of vents near its top. Betweenthese two cylinders is movably mounted a second cylindrical glass sleevelet. The sleeve 14 is spaced from the outer cylinder 13 by spring 15,mounted on the sleeve. Similar springs or spring fingers may also besecured to the inner cylinder 12, if de sired, to space the sleevetherefrom. The upper and lower rings are alike, and the second sleeve isoperated in the same manner as the first or lower sleeve. However, 011the lower edge of this second sleeve are provided resilient clamps 16.These clamps are adapted to engage over the upper edge of the lowersleeve 9, and aline the two sleeves to make a continuous cylinder. Inthis way, the upper sleeve will be steadied when lowered and the lowersleeve will be steadied when raised. Leaf springs (3 may be mounted ingrooves on the outer faces of the lantern body and adapted to engage andhold the rings 8.

The globe of the lantern should be made of crystal or clear glass, oneof the sleeves of red, and the other of green, thus giving the threesignal colors in a single lantern. I Assuming the parts to be in theposition shown in Fig. 1, the operation of the invention is as follows:The leaf spring (3 on the upper outer cylinder 13 will be depressed tofree the upper ring 8. When freed, the upper ring'will be forceddownward, the sleeve 14 sliding freely in the grooves 11, and arryiugwith them the springs clamps 16, which, in lowered position, will engageover the upper edge of the lower glass cylinder or sleeve 9 and lock thetwo in alinement. In its lowermost position, the upper ring 8 will againbe engaged and held by the lower ends of the springs 6.

Changes may be made in the construction. arrangement and disposition ofthe several parts of the invention, without in any way This ring liesdeparting from the field and scope of the same, and it is meant toinclude all such within this application, wherein only a preferred formhas been disclosed.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

l. The combination with a lantern of the character described having aframe and a globe mounted in the frame, a lamp well carried by the framebelow the globe and adapted to support a burner, a grooved ventilatorchimney supported by the frame above the globe, a slide movably mountedin the ventilator chimney and adapted to be moved into and Withdrawnfrom the globe, a ring slidably mounted on the ventilator chimney, rodsconnecting the ring and slide and adapted to travel in the grooves, andmeans for holding the slide in adjusted position.

2. In combination with a lantern of the character described having aframe and a globe mounted in the frame, a lamp well carried by the framebelow the globe and adapted to support a burner, a grooved ventilatorchimney supported by the frame above the globe, a slide movably mountedin the ventilator chimney and adapted to be moved into and withdrawnfrom the globe, a ring slidably mounted on the ventilator chimney, rodsconnecting the ring and slide and adapted to travel in the grooves,means for holding the slide in adjusted position, a second slide mountedin the lamp well and means for holding the slides in alined posi tion.

In witness whereof I have hereunto set my hand in the presence of twowitnesses.
